Description

  The present invention relates to a nuclear magnetic resonance therapy device, ie a device capable of achieving nuclear magnetic resonance for therapeutic purposes in the tissue to be treated.

  Nuclear magnetic resonance therapy devices are known. For example, Patent Document 1 discloses a device capable of achieving nuclear magnetic resonance in a tissue to be treated for the purpose of treatment.

  The device disclosed in this patent has the advantage that the top is open and the user does not have to lie in a tube of some sort to house the toroidal coil.

  Nuclear magnetic resonance therapy devices typically operate at lower magnetic field strengths compared to NMR imaging devices. In the region of tissue to be treated, a magnetic field strength in the mT range produces a magnetic field that is as uniform as possible. This magnetic field consists of a basic quantity and an additional magnetic field swept in a certain quantity, for example in a sawtooth fashion. These magnetic fields define a static magnetic field in the sense of the theory of nuclear magnetic resonance. An alternating magnetic field is applied perpendicular to the static magnetic field, at least during the falling flanks of the sweeping magnetic field, and the frequency of the alternating magnetic field reverses the spins in the tissue to be treated each time the sweeping magnetic field decreases during the sweep. Thus, the magnetic field strength of the sweep magnetic field is adjusted.

  It has been scientifically proven that such treatment can achieve the regeneration of tissue damage, especially cartilage and bone damage. In the cosmetic field for the treatment of cellulite, this form of therapy can be applied as well.

  In particular, great success has been achieved in the area of arthritis treatment. It has been found that this treatment can regenerate cartilage tissue in the same way that cartilage damage can be regenerated.

  Particularly in the treatment of arthritis, it is desirable to provide the largest possible treatment volume, as cartilage damage often spreads over many areas of the body, especially for elderly patients.

German Patent No. 102009060544

  With this background in mind, it is an object of the present invention to provide a nuclear magnetic resonance therapy device that provides the largest possible treatment volume and allows the user to enter in the most comfortable and convenient way possible. That is.

  The device is particularly suitable for arthritis patients with limited movement.

  The object of the invention is already achieved by a nuclear magnetic resonance therapy apparatus according to claim 1.

  Preferred embodiments and further refinements of the invention are specified by the subject matter of the dependent claims.

  The present invention sweeps a magnetic field that spreads as uniformly as possible through the treatment volume, while at the same time irradiating an alternating magnetic field perpendicular to the sweep magnetic field, at least while the sweep magnetic field is decreasing, to provide nuclear magnetic fields in the tissue to be treated. It relates to a nuclear magnetic resonance therapy device, ie a device known from basic principles and described in the introductory part, which can be used to achieve resonance.

  The magnetic field strength of the sweep magnetic field is, in particular, 0.1 mT to 100 mT, preferably 0.3 mT to 3 mT. This is accompanied by a frequency of an alternating magnetic field of 1 mT to 100 mT, preferably 10 kHz to 100 kHz.

  The maximum magnetic field strength of the alternating magnetic field is preferably 0.1 mT to 100 mT, more preferably 0.1 mT to 3 mT.

  To accommodate a patient, the nuclear magnetic resonance therapy apparatus comprises a bed, which is preferably arranged in a substantially horizontal orientation. However, it is likewise conceivable to have some kind of reclining chair, ie in particular a bed where the upper part is inclined at a steeper angle than the lower part.

  On each side of the bed, a respective coil, in particular a sweep coil, is located on the side of the bed, whereby the space between the coils defines the treatment volume.

  These coils are preferably arranged in a substantially Helmholtz configuration, thus producing a substantially uniform magnetic field extending across the bed.

  Preferably, a copper coil with 10 to 300 turns is used as the sweep coil.

  Preferably, the sweep coil alone generates the sweep magnetic field composed of the basic amount and the modulation amount as described above.

  However, it is likewise conceivable that the basic amount of the sweeping magnetic field is generated completely or partially by a permanent magnet, which is preferably likewise arranged on the side of the nuclear magnetic resonance therapy apparatus.

  An alternating magnetic field is generated perpendicular to the sweep magnetic field to generate nuclear magnetic resonance within the treatment volume defined between the sweep coils.

  For this purpose, the nuclear magnetic resonance therapy apparatus according to the invention comprises a first coil for generating a magnetic field, in particular an alternating magnetic field, the first coil being arranged below the bed.

  A second coil, which produces a magnetic field, in particular an alternating magnetic field, is arranged above the treatment volume. Therefore, this second coil is preferably located above or directly adjacent to the sweep coil.

  The first further coil and the second further coil for generating the alternating magnetic field are also preferably arranged in a Helmholtz configuration. During treatment, the coils are placed above and below the patient. As a result, an alternating magnetic field is generated within the treatment volume, which alternating magnetic field has a high magnetic field strength within the entire treatment volume as compared to a single coil that produces the alternating magnetic field over the entire treatment volume.

  Accordingly, the present invention relates to a device for treatment using a magnetic field, which is capable of generating nuclear magnetic resonance in the tissue to be treated, preferably a laterally arranged coil produces a substantially static magnetic field, An alternating magnetic field is generated with two coils perpendicular to its field, one of the coils being located below the user and one being located above.

  However, within the spirit of the invention, a reverse arrangement in which the coils for generating an alternating magnetic field are arranged on the sides and the coils for generating a substantially static magnetic field are arranged above and below the user is likewise conceivable. .

  The coil that produces the alternating magnetic field preferably has substantially the same length as the sweep coil. More specifically, the coils have the same length as the sweep coils plus or minus 20%.

  In another embodiment of the invention, the second coil generating the alternating magnetic field is arranged to pivot upwards or to rise.

  In particular, the upper coil for generating the alternating magnetic field is hingedly mounted on the casing of the sweep coil and can be pivoted upward by an angle of at least 30 degrees, preferably at least 40 degrees. In particular, patients with limited mobility can thus reach the bed more easily.

  In one embodiment of the invention, the upper coil or second coil for generating the alternating magnetic field is in a ring-shaped casing having an inner opening and preferably a substantially rectangular shape when viewed in plan view. Is located in.

  Thus, the casing forms a kind of frame that houses the upper coil that produces the alternating magnetic field.

  The frame preferably has a diameter of less than 200 mm, more preferably less than 100 mm. Therefore, there is a free area inside the frame, whereby the nuclear magnetic resonance therapy apparatus has a wide open upper part despite the presence of the upper coil. The patient lying in the device of the invention thus does not feel so cramped.

  The upper coil above the treatment volume preferably substantially follows the shape of the bed, and in particular extends over 70% of the bed surface.

  The coil for generating the alternating magnetic field and / or the coil for generating the sweeping magnetic field can in particular be arranged in a casing, which casing has side faces parallel to each other in its main extension direction, in which the coil is On the narrow side, the coils extend arcuately, in particular in the form of an arc, on a narrow side. The casing preferably has at least a central opening.

  In this way, it is possible in a simple manner to generate a large magnetic field adapted to the treatment volume located above the bed.

  In a preferred embodiment of the invention, two coils, in particular a sweep coil and a second further coil, which preferably serves to generate an alternating magnetic field, are mounted on a ramp which can be pivoted upwards. .

  Therefore, according to this embodiment of the invention, two coils out of a total of four coils, which serve to generate nuclear magnetic resonance in the treatment volume, are pivoted upward together, which is preferred by the user. It is contemplated that can easily enter the device in the form of a bed.

  In particular, it is contemplated that the ramp is coupled to the rest of the device via a pivot joint.

  To provide a large access area, the ramp is adapted to pivot upward by an angle of at least 50 degrees, preferably at least 70 degrees, according to a preferred embodiment of the present invention.

  The ramp can be held in the upward pivoted position by a spring, in particular by a traction gas spring. Such springs can ensure easy up and down pivoting.

  Preferably, the device comprises at least two, more preferably four traction springs. This can ensure that, for example, if one traction spring fails, the entire weight of the ramp with the two coils will not fall.

  According to one refinement of the invention, the ramp comprises at least one operating unit, in particular a screen, which can be provided, for example, in the form of a touch screen.

  The operating unit can in particular be arranged in the upper corner of the ramp, and according to a preferred embodiment the operating unit is inclined with respect to both the horizontal and the vertical plane, so that it faces the operator of the device. It is arranged diagonally.

  More specifically, the surface of the screen can be inclined at an angle of 20 to 80 degrees, preferably 30 to 70 degrees with respect to the vertical plane.

  The ramp can further have an electronically controlled component arranged therein, in particular a control unit for controlling the coil. The heavy components of the control unit are preferably located below the bed surface of the device rather than in the movable ramp.

  In a refinement of the invention, at least one coil is embedded in the potting compound, i.e. the potting compound.

  In particular, it is contemplated that the coil is introduced into a casing, preferably made of plastic material, and embedded with a potting compound.

  The use of the potting compound prevents the coil from moving, especially due to Lorentz forces. In particular, annoying noise can be eliminated in this way.

  Fiber-reinforced composite materials, in particular GFRP or CFRP, are preferably used as plastic for the casing.

  In a further embodiment of the invention the device comprises a replaceable bed surface. Thus, the bed surface can be exchanged for another bed surface of different shape or with other functional treatment components, such as straps for fixing body parts.

  In a further embodiment of the invention, the device comprises variable color lighting means, which lighting means are preferably provided in the form of LED light strips.

  It is specifically intended that the color of the light changes during operation of the device, ie when nuclear magnetic resonance is being generated.

  Furthermore, the treatment volume is marked with the illumination means, for example by having two light strips projecting laterally elongated light onto the bed surface, which are arranged above the second further coil. be able to.

  In a further embodiment of the invention, the device is for measuring the amperage of one of the coils and / or the frequency of the alternating magnetic field generated by at least one of the coils, at least upon activation of the device. With the control unit used.

  This embodiment of the invention takes advantage of the fact that, for a sweep field, the field strength of the sweep field is a function of amperage.

  Therefore, it is possible to inspect whether or not the magnetic field strength of the sweep magnetic field is within the target range by measuring the amperage.

  If the error does not fall within the target range, the achievement of a resonance condition in the treatment volume is not guaranteed and the device issues an error message and stops the treatment.

  Preferably, the alternating magnetic field is also controlled with respect to its frequency.

  According to a preferred embodiment of the present invention, the frequency and / or amperage of the alternating magnetic field is controlled during ongoing operation as well.

  In a preferred embodiment of the invention, the amperage test and / or the frequency of the alternating magnetic field are checked individually for each coil. Therefore, in the case of an error, the cause of the error can be easily determined.

  In a further embodiment of the invention, the device comprises a sensor, in particular configured as a switch, by means of which sensor it is closed or not, i.e. in particular in a position in which the ramp is pivoted below it. It is inspected for the existence.

  Thus, treatment can only be performed when the coils are in the correct position relative to each other, not when the device is partially open.

  In one embodiment of the invention, the control unit comprises a timer that stops the time when the treatment is interrupted, and when the device is restarted, until the total treatment time entered or stored is reached. To continue. This ensures that the desired treatment time is exactly achieved, even if the treatment is interrupted.

  In one embodiment of the invention, the sweep coils are each located on a side adjacent the bed, one of the sides being configured to descend or pivot upwards.

  In the first embodiment of the present invention, the side that houses the sweep coil is preferably movable downward so that it does not substantially project beyond the bed surface in the lowered state. With the sides lowered and the casing of the upper coil generating the alternating magnetic field optionally pivoted upwards, the patient or user can easily enter the nuclear magnetic resonance therapy apparatus.

  Preferably, only one side is configured to descend or pivot upwards. Thus, this mechanism is only required on one side, for example the device can be placed with the fixed side against the wall.

  In one embodiment of the invention, the lower portion of the sweep coil has a linear shape and the upper portion of the sweep coil has a curved shape. In particular, the sweep coil essentially has the shape of a partially arcuate window. Therefore, the contour of the sweep coil is composed of a rectangle and an arc or elliptical portion.

  This shape approximates the user's anatomy. In the posterior region and the anterior region, ie in the region where the extremities are placed during treatment, the required treatment volume is smaller than the central region.

  The partial arc has, in particular, a radius of 1 m to 2 m.

  In one embodiment of the invention, the bed is part of a removable module, which can rotate about 180 degrees and comprises at least a first coil for generating an alternating magnetic field. In particular, the module containing the bed also comprises a control unit for driving the coils and an operating unit. The operating unit is preferably arranged on the front side or the rear side.

  The module comprising the bed and the control unit can be connected to other coils, i.e. to the sweep coil, and to the upper second coil which produces an alternating magnetic field.

  Depending on where the device of the invention is placed, the module can be installed with the bed rotated about 180 degrees, in particular so that the operating panel or the headrest of the bed is placed on the desired side.

  FIG. 1 is a perspective view of a first embodiment of a nuclear magnetic resonance therapy apparatus 1.

  The nuclear magnetic resonance therapy apparatus 1 of this embodiment comprises a bed 20 having a bed surface 2 on which a user can lie.

  The bed 20 is arranged on a table 21.

  Adjacent to the bed 20 are coil casings 23a, 23b, which, in this exemplary embodiment, comprise the coils used to generate the swept magnetic field.

  The coil casings 23a, 23b have a substantially rectangular central portion with the longitudinal edges of the casings 23a, 23b extending parallel to each other. On the narrow side, the casings 23a, 23b have a curved design in the form of an arc in this embodiment.

  In this way, it is possible to provide the coil casings 23a and 23b that have substantially the same length as the bed surface 2 and can provide a large treatment volume.

  The treatment volume is defined by the volume between the coil casings 23a and 23b and the area between the bed surface 2 and the coil casing 24.

  The bed 20 houses a coil that generates an alternating magnetic field.

  A further coil for generating an alternating magnetic field is arranged in the coil casing 24 arranged above the coil casings 23a and 23b.

  The coil casing 24 also has an elongated shape with a curvilinear narrow side.

  The bed 20 likewise has a curvilinear narrow side, which accommodates a coil (not shown here) having a shape substantially corresponding to the coil in the coil casing.

  The coils within the coil casing 24 are also used to generate the alternating magnetic field.

  The coils within the bed 20 and the coils within the coil casing 24 are arranged in a Helmholtz configuration to create an alternating magnetic field of uniform magnetic field strength within the treatment volume.

  In this way, the systemic treatment of the user is possible in a simple way.

  All coil casings 23a, 23b, 24 have openings 36, which are intended to alleviate claustrophobia of the user, especially during treatment.

  In order to be able to enter the device, the device 1 of this exemplary embodiment comprises a sloping part 22, which comprises a pivot joint 25 arranged substantially in the center and provided in the form of a hinge. Can be pivoted upwards to the center.

  An upper coil coil casing 24 is attached to the inclined portion 22 above the treatment volume, and a sweep coil coil casing 23b is attached to the front side of the inclined portion 22.

  When the inclined portion 22 is pivoted upward, both the coil casing 23b and the coil casing 24 are pivoted upward simultaneously, and the user can easily reach the bed surface 2.

  A handle 37 is provided below the inclined portion 22 so that the device 1 can be easily opened and closed.

  The inclined portion 22 extends across only a part of the opening 36.

  A screen 26 is arranged in the upper corner of the ramp 22 and the screen 26 is preferably designed as a touch screen. A control unit (not shown) can also be arranged on the ramp.

  The surface of the screen or screen 26 is inclined at an angle of 30 to 70 degrees with respect to the vertical plane so that the screen, which is preferably provided in the form of a touch screen, is easily accessible. .

  Other control components such as a card reader can also be located in this area.

  The bed surface 2 can be removed and replaced with another bed surface (not shown) with additional treatment components.

  2 is a rear perspective view of the device 1 shown in FIG.

  As can be seen in particular in this figure, the device 1 comprises a rear part 27 connected to a pedestal 21, the rear part being fitted with a coil casing 23a on one side and a pivot joint 25 on the other side. There is.

  The rear portion 27 extends upward in the center, in this embodiment as a kind of post.

  It will be appreciated that the control components of the device 1 can likewise be arranged in the rear part 27.

  FIG. 3 is a perspective wire frame diagram showing the hinge 25 in particular.

  The ramp 22 is composed of a housing, in which a beam 30, preferably a metal beam 30, is embedded.

  These beams 30 are pivotally mounted on a pivot joint 25.

  Respective arms 28a and 28b are provided on the opposite side of the pivot axis from the beam 30.

  Each of the arms 28a and 28b is connected to two traction gas springs 29a, 29b and 29c, 29d, respectively.

  The traction gas springs 29a to 29d can easily pivot the inclined portion 22 upward. The downward pivoting of the arms 28a and 28b relative to the traction gas springs 29a-29d causes the lever arm to extend so that in the fully open state the traction gas springs 29a-29d are higher than in the closed state of the device. With force, the device will automatically remain open.

  FIG. 4 shows a perspective view with all housing components and parts of the bed omitted.

  Thus, the coils 9 and 10 can be seen, they are arranged in a Helmholtz configuration and serve to generate the swept magnetic field.

  An alternating magnetic field is applied using a coil 10a arranged below the bed and a coil 10b arranged above the bed, and the alternating magnetic field spreads perpendicular to the sweep magnetic field.

  The beam 30 can be seen, the beam 30 has a squared shape and is attached to the pivot joint 25.

  Below the pivot joint 25, a rod 34 is attached, the ends of the traction gas spring being attached to this rod, thus defining a further pivot joint 31.

  The frame 32 comprises support beams for both the rear and the bed.

  The beams 30 connected to each other and hingedly attached to the frame 32 form a ridge 33 on the front side, behind the ridge 33 the upper part of the coil 10 extends.

  As suggested by one embodiment of the present invention, the metal components of frame 32 and beam 30 may be insulated from each other to minimize current induction.

  FIG. 5 shows a detail of FIG. 4, in which the area of the pivot joint 25 is clearly visible from the rear side.

  In particular, one can see the rear arms 28a and 28b facing the beam 30, to which the traction gas springs 29a to 29d are attached.

  Furthermore, the rotatable rod 34 can be seen, which serves as a counter bearing for the lower ends of the gas springs 29a-29d.

  It will be appreciated that instead of a rotatable rod, it is likewise possible, as an alternative, that each lower end of the traction gas springs 29a-29d be rotatably mounted on the rod.

  Two traction gas springs are provided for each arm 28a, 28b. The use of multiple traction gas springs is particularly advantageous, because even if the traction gas spring fails, the total weight of the ramp cannot drop. Otherwise, such a drop would carry the risk of damage.

  FIG. 6 is a wireframe diagram of the area of the pivot joint 25.

  The housing part 35 of the ramp 22 that extends around the beam 30 can be seen. The pivot joint 25 is shown in the open state in this figure.

  The housing part 35 has a circular cylindrical shape in the area of the pivot joint 25 and rotates in a corresponding recess of the rear part 27.

  FIG. 7 is a perspective view of the nuclear magnetic resonance therapy apparatus 1 in an open state.

  As can be seen, the ramp 22 supporting the two coils is pivoted upwards about 90 degrees. This ensures that the treatment volume is easily accessible.

  According to one embodiment of the present invention, the opening angle can be adjusted by the operator of the device 1, for example so that the maximum height of the handle 37 can be adjusted for different operators.

  Further, in this exemplary embodiment, the ramp 22 comprises light strips 38 that face each other. In this view, only one light strip 38 can be seen. Opposing light strips are arranged on the other side of the ramp 22 above the bed surface. The light strip 38 is preferably designed as a variable color LED illumination.

  The light strip 38 can serve to mark the treatment volume and can also indicate whether the device 1 is in operation. For example, the color of the illumination can be changed when the device 1 is activated.

  FIG. 8 shows a perspective view of a further embodiment of the nuclear magnetic resonance therapy apparatus 1.

  The nuclear magnetic resonance therapy apparatus 1 comprises a bed 2 arranged horizontally in this embodiment, so that the patient to be treated (not shown) can lie on the bed 2 whole body.

  The bed 2 is part of a module with a housing 3. Adjacent to the bed 2 and adjacent to the housing 3, side walls 5 and 6 are arranged. The side walls 5 and 6 house sweep coils, as described in detail below.

  Furthermore, the outer housing 7 can be seen in this figure, which is part of the housing housing the side wall 6.

  A coil casing 8 for generating an alternating magnetic field is arranged above the side walls 5 and 6.

  Below the bed 2 there are arranged additional coils, which cannot be seen here, which generate an alternating magnetic field.

  Furthermore, the module with bed comprises a control unit 4 arranged at the front end of this module.

  FIG. 9 is a wireframe diagram of the nuclear magnetic resonance therapy apparatus 1 shown in FIG. 8, in which a hidden edge, that is, the inside of the nuclear magnetic resonance therapy apparatus 1 can be seen as in an X-ray image. it can.

  Here we can see the two sweeping coils 9 and 10 arranged in the side walls 5,6.

  Furthermore, in this figure, the side wall 6 is arranged between the two posts 16, 17 to allow the side wall 6 to be moved downwards, whereby the sweep coil 10 is shown in position 10a. ing.

  Various technical options are conceivable for moving the side downwards, i.e. for lowering. For example, manual lowering is possible. For this purpose, the sides can run on rails and can be connected to the counterweight by cables and pulleys. The counterweight prevents the sides from falling and allows the sides to be easily raised and lowered manually.

  Furthermore, electric actuation, for example using a spindle drive, is likewise conceivable.

  The sweep coils 9 and 10 are arranged opposite each other in a Helmholtz configuration and cover most of the length of the bed surface.

  The coil casing 8 also extends across substantially the entire width of the bed, over most of the length of the bed.

  FIG. 10 shows the nuclear magnetic resonance therapy apparatus 1 shown in FIGS. 8 and 9, in which an upper coil casing 8 including coils for generating an alternating magnetic field is pivoted upward. For this purpose, the coil casing 8 is hingedly mounted on the side wall 5.

  When the side wall 6 is lowered here, the user 11 can easily enter the nuclear magnetic resonance therapy apparatus.

  FIG. 11 shows a further perspective view of the nuclear magnetic resonance therapy apparatus, in which the bed surface of the housing 3, which is designed as a module, has been removed.

  It can be seen here that the coil 12 for generating the alternating magnetic field is likewise arranged below the bed surface. This coil is synchronized with the upper coil which produces an alternating magnetic field in a Helmholtz configuration.

  Here, in the treatment volume, an alternating magnetic field with a very uniform magnetic field strength is achieved, which overlaps perpendicularly to the magnetic field of the sweep coil located on the side.

  FIG. 12 is a diagram of a nuclear magnetic resonance therapy apparatus 1 in which the sweep coils 9 and 10 can be seen, between which the treatment volume is defined above the bed 2.

  FIG. 13 shows the configuration of the sweep coil.

  The sweep coil has the shape of a partially arcuate window, that is, it has a rectangular lower portion and a curved upper portion, and between the arc and the lower portion, the coil has a straight portion.

  However, it is likewise conceivable to design the coil as a partial arc and / or to round off at least the angled areas.

  FIG. 14 shows the coil casings 8, 15 of the upper coil and / or the lower coil generating the alternating magnetic field.

  The coil casing has a substantially rectangular ring-shaped shape and is substantially adapted to the shape of the bed surface. A housing with a central opening houses the coil 12 which produces an alternating magnetic field.

  FIG. 15 shows a housing 3 of a bed surface module, which comprises a headrest 13 and a storage slot 14 at the opposite end for a control unit (control unit 4 in FIG. 8).

  The module can be rotated about 180 degrees so that the control unit is located on the desired side.

  FIG. 16 shows a cross-sectional view of the nuclear magnetic resonance therapy apparatus 1. Here, one can see the coil casing 15 arranged below the bed surface, which houses the lower coil for generating the alternating magnetic field. The side wall 5 can also be seen, in which the sweep coil is arranged.

  The treatment volume extends from the coil casing 15 above the bed and is located between the side walls.

  Furthermore, in a variant of the alternative embodiment not shown in the drawings, the side wall indicated by reference numeral 6 is connected to the upper coil casing (reference numeral 8) and can be pivoted upward together with the upper coil casing.

  The present invention has been able to provide a nuclear magnetic resonance therapy device that can achieve a wide therapeutic area and in particular allows systemic treatment and provides a patient with simplified access.
